Diamond H Ranch #18H (API 42-127-35651) is a horizontal well in Dimmit County operated by Javelin Energy Partners Mgmt LLC, completed December 23, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 8, 2013, permitted to 7,492 ft.
It was permitted by Anadarko E&P Onshore LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its 2 leases have reported 7.16M barrels of oil and 15.8M mcf of gas since June 2010, last reporting volume in April 2026. The leases carry 46 wells, so these are lease totals, not this well alone.
